The present invention provides a dimming backlight partition dimming control method, an intelligent terminal and a storage medium, and a dimming backlight partition dimming control method, which is used for partitioning and regulating the brightness of the backlight source of the smart terminal, which includes the intelligent terminal motherboard SOC to obtain image partition information , and brightness information corresponding to the image partition information, and send the image partition information and brightness information to the FPGA; the FPGA receives and parses the image partition information and brightness information, and generates a partition control signal according to the image partition information and brightness information, and at the same time, sends The partition control signal is sent to the driver chip; the driver chip receives the partition control signal, and drives and controls the brightness of the image partition according to the partition control signal. The display screen and brightness information are obtained through the SOC of the intelligent terminal motherboard, and then the driver chips corresponding to the dimming and backlight partitions are uniformly controlled by the FPGA, which improves the dimming efficiency and dimming effect of the dimming and backlight partitions.
